The production of dijets in diffractive deep inelastic scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 61 pb{sup -1}. The dijet cross section has been measured for virtualities of the exchanged virtual photon, 5 < Q{sup 2} < 100 GeV{sup 2}, and {gamma}*p center-of-mass energies, 100 < W < 250 GeV. The jets, identified using the inclusive k{sub T} algorithm in the {gamma}*p frame, were required to have a transverse energy E*{sub T,jet} > 4 GeV and the jet with the highest transverse energy was required to have E*{sub T,jet} > 5 GeV. All jets were required to be in the pseudorapidity range -3.5 < {eta}*{sub jet} < 0. The differential cross sections are compared to leading-order predictions and next-to-leading-order QCD calculations based on recent diffractive parton densities extracted from inclusive diffractive deep inelastic scattering data.
